' Applieationiiiled March 27 1399- Be Yit known that we,'1-1ENRYPEECIVAL GAMBLEand ARTHUR BLACK,` subjects of the Queen of Great Britain, residing atLeicester, England, have invented certain new and useful Improvements in or Relating to Heelin-g Machinery, (for which Letters Patent have been applied for in Great Britain, No; 19,079, dated/September 7 1898,) of which the following 'is aspecification. n

This invention relates vto, heeling-machin'- ery employed in the manufacture `of boots and shoes, and has for its object to provide heel building or attaching machines' with mechanism for automatically feeding the horn of such machines with the nailsby which the Y heels are attached toa boot orshoe.

The invention will be understood from the following further' description in referenceto the accompanying drawings, infwhich- Figure 1 is a longitudinal section on the line A A of Fig. 3. Fig. Zisatransverse section'on the line B B of the same figure, and Fig. 3 is a plan of the automatic feeding apparatus for heeling-lnachines constructed in accordance with this invention. Fig.' 4 is a longitudinal section on the line X X of Fig. 1. Fig. 5 is an elevation of the rack-and-pinion mechanism for actuatingv the transverse slides and shutters of the nail-chutes. Fig. 6 is a detail View showing the nail elevating and delivery slides after the former has raised its nails out of the hopper and transferred them to thelatter. Figs. 7, 8, and9 are plans of. parts of the transverse slides in different positions. Figs. 10 and 11 are details of the nail-chutes and shutters therefor. Fig.` 12 is a detail view of the nail-receiver and a horn of a heeling-machine inl the act of receiving nails from the former. Fig. 13 is a perspective View, partly broken away, of our in venition.

The parts of a heeling-machine necessary toa'clear understanding of the inventionare shown in dotted lines.y

A represents a'rectangular box or casing which is xed transversely over another box or casing B', which latter is carried by upright arms C, bolted at C to the bed-plate C2 of a heeling-machine.

The box A contains the main supply of most clearly indicated in Fig. 2.

'serial 10.710,655. une mean.)

nails and may be divided into compartments or hoppers, three, A2 A8 A4, being shown, as

Each hopper has aninclined platform A5, so that the heel-nails when placed therein descend of ltheirown Weight to the bottom and-in the path of a vertical nail-elevating slide D. An

inclined plate A near the open upper end of the hopper causes any nails which fall thereon when thelatteris being filled to slide onto the platform A5. Another inclined plate AT is located under the platform A5, so that when it is desiredto change lthe size or gage oi. the nails already in the'hopper the latter may vbe quickly emptied by withdrawing the said plate A5,'whereupon the nails will fall en' masseonto the plate A7 and roll down it and through the open end As of the box into areceptacle which the operator may place or hold to receive them. Each of the three plates A5 A6 A7 stretches across the full width of the hopper and lits movably in grooves formed on the inner-surface ofthe sides of the said The box A is attached to the box Bby screws Agand angle-plates A10.

The door of each hopper is formed by the upper edge of the nail-elevating slide or selector D, which, as shown, consists of a thin metal plate, each side of which is located in a groove in the side of y the box. The lower end of this selector is attached by means of an angle-plate A11 and screws A12 to a cross-bar A13, and the latter is attached at each end by a screw A14 to the upper. end of a vertical rack E, located in grooved guide-plates lE', fastened by screws E2, Figs't and 6, to the inner face of the box B'. A'plate E3, screwed over the open side-of the guides,keeps the rack from displacement by any vibration or shock during the Workin g of the machine.

The two vertical racks E maybe connected Y by a cross-head and the latter attached centrally to thel connecting-rod C5 from a foottreadle C4, or the said connecting-rod maybe attached to the endof one of thesaid racks, as shown in Fig. 1. A spring C? is connected IOC) their lowest positions; but immediately the operator removes his 'foot from the treadle the spring raises the latter, the connectingrod C3, racks E, cross-bar A13, and the nailelevating slide D, and the latter in moving upward in the hopper in which the heelnails are contained lifts some of the latter with it on its upper edge.

The nail-elevator slide is located parallel to and close against a delivery-slide F, and as it rises, carrying on its upper edge the selected nails, the latter are prevented falling off by bearing against the side of this slide. When the upper edge of the elevator-slide becomes coincident or in register with the upper edge of the slide F,the nails, which are lying lengthwise, roll off the inclined edge of the elevator onto the inclined upper edge of the adjacent slide. This latter slide moves in grooves in the sides of the box, and when in its normal position-that is, when the elevator is at its lowest point (indicated in Fig. 2)-its upper edge is situate just above the upper edge of a parallel partition G, over which, as hereinafter described, it delivers the nails. Vhen, however, the elevatorslide commences to ascend, the slide F falls down below the upper edge of the partition into the position indicated in Fig. 6 preparatory to receiving onits upper edge the nails as they roll off the elevator-slide. It will be observed that when the said slide is in this lowered position a space or narrow chamber is formed between the partition G andthe elevator-slide D, and as the nails drop onto the edge of the said slide F they are pre vented falling off by the partition on the one side and the elevator-slide on the other side.

The delivery-slide F is supported on the top of a vertical lever F', the upper end of which passes through a guide-slot in the bar II, to be described,wliile the lower end is pivoted to a short lever F2, fulcrumed to a short arm F3, projecting from the inner side of the box B.

When the nail-elevator is in its lowest position at the vbottom of the hopper, as shown in Figs. 1 and 2, the corner of the foot D' of the former rests on the lever F2 to the right of its center, and acting as a counterweight presses down that end of the lever and raises its other end, which lherebyelevates the vertical lever F', and the latter raises the pindelivery slide F, which rests thereon, into the position shown in Fig. 2, where it parts with the nails on its upper edge, the said pins rollingT over the partition G, as hereinbefore described. As the nail elevating slide commences to ascend, and thereby removes its foot off the lever F2, the delivery-slide drops of its own weight into its lower position, Fig.L 6, hereinbefore described, in readiness to receive the nails from the ascending elevatorslide, and in doing so depresses the vertical lever F' and raises the end of the other lever F2 into a position where the latter will again be actuated by the foot of the eleif'ator-slide when the latter descends. When the delivery-slide has parted with its nails over the side of the partition, the nails fall into a passage formed between it and a similar partition or plate G', also iitted ina groove in each side of the box A'. The plate G' has an up- .per horizontal extension G2, forming a cover to the passage between them, so as to prevent any nails shooting over the top when being delivered by the slide F, and a shutter or flap G3 closes the opening above the delivery-slide and passage and prevents any nails which when being delivered strike the plate G2 rebounding into the hopper.

The shutter G3 is loosely hung on pins or trunnions resting loosely in the upper edge of the sides of the box A', and on its lower end it is provided with a curved wire G4 or equivalent, which when the nailelevator slide ascends will be moved on one side, thereby, as in Fig. 6, to let the latter pass, and will swing back of its own accord into the position shown in Fig. 2 when the elevator-slide descends.

The width of the passage between G and G' is approximately that of the thickness of the nails, and when the latter drop down the same they fall point downward into a space between two parallel bars H H and become suspended by their heads and point downward, as indicated in Fig. 6. These bars are let into the ends of the box B' and are secured thereto by screws B2, Fig. 3. Between each pair of bars is a slide J, the function of which is to move forward the nails hanging between the said bars until they drop through the end thereof, as hereinafter described. This slide is connected by means of a spring J' to an extension K' of a vertical arm K, which rises upwardly from a plate K2, attached transversely to a slide or carriage L. This carriage has attached to it two transverse plates Y2 K3, each of Vwhich has tubular ends iitting easily over two fixed shafts or guide-rods K4, the ends of which are fitted in the ends of the box B'.

The nail-traversing slide .l is provided with a tailpiece J2, bearing against the vertical arm K, and when the carriage L makes its return movement the said vertical arm returns the slide to its original position.

The carriage on its forward end has fixed thereto a receiver L', consisting of a block having therein a number of holes L2 for the reception of heel-nails, the said holes corresponding in number and position to those in the usual horn of a heeling-machine, and when the said receiver has returned to its original position the nails which were pushed to the ends of the bars drop thereinto as follows: The spaces between the bars H H' are continued into and have their termini between two slides M M', which have a transverse movement, whereby the nails drop into chutes underneath them. The said slides consist of two plates placed one above the other and slotted to pass over a block N (shown only IOO IIO

in dotted lines in Figs. 7, S, and 9) shorter than thel slot and covered bya plateN', which also overlaps the uppermost slide M and is tixed in position by screws N2, passing into the end of the box B'. The fact of the block N being shorter than the slot and slightly thicker than the combined depths of the two transverse slides permits the movement of the latter, as will be described. The terminus of the passagebetween the bars H H' is formed between the two slides M M'-, and when two heel-nails are movedv by the slide J into the said terminal passage, as shown in Fig. 7, one

'lower slide M. on the one side and the end of the bar H or H' on the other side. When the two slidesv move together tothe right, the passage between the lower slide and the adjacent bar is widened, and the nail suspended between immediately drops into the' chamber underneath,but the other nail is carried between the two slides, as shown in Fig. 8,1mtil the uppermost plate M comes into contact with a stop-pin B3, passing through the side of the box B', when the lower of the two slides moves alone a short distance, thereby increasing the width of the terminal passage, as in Fig. 9, so that. the nail held between the slides drops into the other chamber bellow. This movement of the slides is obtained as follows On the underside of the lower slide are two downwardly depending pins M2 M3, which embrace an arm O',projecting outwardly from a horizontal slide-rack O, moving in a recess or' guideway formed in the frontend of the box B. This slide-rack obtains its motion in one direction from an arm P',- bearing thereagainst and connected to a vertical spindle P, mounted rotatably in lugs B4 B5, connected to the side of the box B'. The lower end of the said spindle is also furnished with an arm P2, located in the track of a projection L3, secured to the side of the carriageL. When the latter moves into the box, the projection L3 moves the arm P2out of its way, thereby causi ing the upper arm P' to press against the end of the slide-rack O and move it toward the opposite side. The said slide-rack O obtains its motion in the return direction from an arm Q', pressing against its other end and attached to a vertical spindle Q, also mounted rotatably in lugs B6 B7, attached to the other side of the box B', and also furnished, on its lower end with an arm Q2, which on the carriage moving into the box comes into contact with a projection L4 thereon, which moves the said arm Q2 out of its track, rotates'the spindle Q, and causes the upper arm Q' to press with sufficient force against the end of the sliderack O to move it toward the other side of the box. The return movement of the upper slide-rack O takes the arm P' back to its.

tached to it by screws R' a shutter R for each of the nail-chutes S, leading to the receiver L' from that side of the box B'. chutes S on the opposite side are also furnished with shutters R, connected by screws R2 to an armT', projecting from another slide-rack T, which obtains its motion from a pinion T2 in gear therewith and also gearing with the upper slide-rack O, from which it is actuated. Reverting now to the transverse slides M lvl', it will be yobserved that these receive their motion in the one direction to allow the nails to drop into the chutes thereunder, as here- `inbefore described, from the arm 0' pressing against the downwardly-depending pin M3 and in the return direction to the position ready to receive a further supply of nails from p shutter is withdrawn the nails fall head downintegrally with a back plate S2, secured by. screws S3 to the bars H, and the chutes S are4 fixed by screws S4 to the under side of the back plate S2.

. The floor of the receiver consists ofv a shut-v ter U, provided with a number 'of throughperforations corresponding in number and position to the holes Lzin the receiver. The shutter is furnished with a downwardly-depending lip U"and with a spring U2, which 'maintains the shutter in such a position on The 7 IIO the receiver that the holes in the two are'not in register. y

When the receiver is moved outwardly over the usual horn of a heeling-machina as in Fig. 12, the lip on the receiver'comesinto vcontact with the edge of horn C6 andarrests the motion of the shutter just before the termination of the movement of the receiver, and

immediately theholes in the receiver and its the heeling-machine, which'becomes thus automatically fedV thereby. i

The receiverl and carriage L receive their motion from a rack L5 on the under side of the latter gearing with a spur-wheel V', lo- A tuated by the foot-treadle G4, as hereinbefore described.

VThe action of the machine is as follows:

Upon the operator lifting his foot oit the treadle the spring G5 raises the latter and the connecting-rod O3, which elevates the racks E, the cross-bar A13, attached thereto, and also the nail-elevator slide D. The latter carries on its upper edge some of the nails in the hopper and immediately upon commencing to rise removes its foot off the lever F2, which thereby allows the adjacent slide F to drop, so that its upper edge is below the partition G, as in Fig. t). lVhen the nail-elevator slide in ascending passes above the delivery-slide F, the nails roll oft the former onto the latter. Upon the operator again depressing the treadle the racks and elevator-slide are lowered, and the latter in descending drops its foot upon the lever F2, which thereupon raises the vertical lever F and slide F., and the latter discharges its nails over the top of the partition G, when they drop between the bars ll ll' and become suspended by their heads, as hereinbefore described. Simultaneously with the raising of the said racks the latter rotate the pinions V2 and the shaft V, and the central spur-wheel V thereon engages the rack L5 on the under side ot the carriage L, thereby traversing the latter outwardly of the box, takingwith it the upright arm K, connected to the slide J. The latter is thereby caused to move along between the bars H H' and push the nails suspended therebetween to the end of the passage and into the termini thereof formed in the transverse slides M M. As the carriage L and the receiver return, the projec` tion on the former collides with and moves the arm P2 out of its patlnthereby rotating the vertical spindle l? and causing the arm F on the upper end thereof to press against the upper rack-slide O and move it along. The arm O on the latter thereupon moves the depending pin M3 and the latter moves the two transverse slides M M in the same direction. The bottom slide M' upon passing away from the bars H H' allows the heel-nail which was suspended between it and the latter to drop into the chamber at the top of one of the chutes immediately beneath and to rest against the shutter R, as in Fig. lO, while another nail is carried between the two slides until the top slide comes into contact with the stop-pin B3, which arrests its progress while the lowerslide moves a short distance per se, thus enlarging the space between them, so that the nail they carried now drops into the chamber of another chute immediately underneath. At the same time that the arm O' moves the slides M M as described it moves the shutters R intol Ithe chambers of the nail-chutes S on one side, and the pinion T2, rotated by the upper rack O', traverses the bottom rack K and the latter moves the shutters R into the chambers of the nail-chutes on the other side, so that the nails which have dropped as the result of the movement of the transverse slide now re- 'main supported onv the said shutters, as described, and shown in Fig. 10. Just prior to the carriage L completing its inward movement the projection Ll collides with the arm Q2 and in passingmoves it so that it rotates the vertical spindle Q and arm Q on the up. per end thereof, and the said arm moves the slide-rack' O and the latter, through the medium of the pinion T2, moves the lower sliderack T, so that the two racks withdraw the shutters and let the heel-nails fall head fore most down the nail-chutes S just as the receiver L arrives in position thereunder to receive them. Upon the loaded receiver coming forward the next time the lip U' of the shutter strikes the horn C(j of the heeling-maL chine and is arrested in its motion while the receiver moves per se slightly in advance until the holes in the shutter and the receiver are in register,I when the nails drop through the latter and into the holes in the horn, as shown in Fig. l2.

Ilaving now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim isl. In a machine of the characterdescribed the combination of a hopper, a nail-elevating slide therein, an adjacent slide for intercepting the nails off the latter, and discharging them, two or more bars arranged with spaces between for the reception of the said nails, a slide for moving the nails forward between the bars, transverse slides for intercepting the nails and dropping them into nail-chutes, a receiver located under the latter for the rei ception of the nails and adapted to be moved forward and discharge the said nails into the horn of a heeling-machine substantially as described. 1
